1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

BackgroundChronic obstructive pulmonary disease (COPD) is associated with alterations in brain function that contribute to reduced respiratory and skeletal muscle strength, ultimately limiting exercise capacity. Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique, has demonstrated efficacy in enhancing lower extremity function in healthy older adults.ObjectiveTo evaluate the effects of a single session of anodal tDCS on exercise capacity, respiratory muscle strength, and physical performance in individuals with COPD.MethodsIn a randomized, double-blind, sham-controlled trial, 26 participants with COPD underwent baseline assessments of exercise capacity (Six-Minute Walk Distance, 6MWD), respiratory muscle strength (Maximum Inspiratory Pressure, MIP), and physical performance (4-m Gait Speed, 4MGS). Participants then received either active or sham tDCS, followed by reassessment 1 day post-intervention.ResultsCompared to sham, the active tDCS group showed significant improvements in physical performance, including increases of 46 ± 11.45 m in 6MWD (
